Automated QA testing: unit, integration & E2E

At Lasting Dynamics, we consider automated QA testing the foundation of reliable software. By combining multiple levels of testing, we ensure both robustness and scalability across every release.

We start at the code level with unit tests, validating each component or function to guarantee it performs as intended. Then, through integration testing, we verify that modules work seamlessly together and deliver the expected combined behavior.

Finally, our end-to-end tests (E2E) replicate real-world user scenarios, validating the entire application from start to finish. This layered approach allows us to catch regressions early, reduce risks, and maintain long-term quality in complex digital products.

Performance testing for scalable software

Application performance can quickly become a bottleneck when scaling to thousands of users or supporting large public-sector projects. At Lasting Dynamics, we deliver performance testing services designed to validate stability, responsiveness, and scalability under any condition.

Our QA engineers simulate real-world user loads and traffic spikes, measuring response times, throughput, and resource utilization. By combining load, stress, spike, endurance, and volume testing, we identify potential bottlenecks before they impact end users.

This structured approach not only improves system reliability but also ensures that your applications can handle growth, maintain efficiency, and deliver a smooth experience—even under massive adoption.

UI Testing services for seamless user experiences

Our UI testing services ensure that every interface is intuitive, accessible, and visually consistent across devices and resolutions. We validate both individual UI components in isolation and their behavior within the overall system, guaranteeing smooth interactions and a reliable user journey.

Regression testing services for reliable releases

Regression testing ensures that new updates don’t break existing features. At Lasting Dynamics, we provide automated and manual regression testing services to detect issues early, prevent costly bugs, and guarantee seamless functionality across every release.

Our QA team maintains dedicated test suites, version control, and impact analysis to quickly identify risks and validate fixes. This rigorous process not only safeguards product stability but also builds long-term trust, allowing businesses to scale with confidence.

White box testing

White box testing (also called structural testing) validates the internal logic, design, and code of an application. By analyzing input-output flows, verifying conditions, and checking paths, our QA team ensures robust functionality, improved security, and optimized design. Since the code is visible to testers, this method helps detect hidden logic errors early in development.

Black box testing

Black box testing (also known as functional testing) focuses on the external behavior of the software, without requiring knowledge of its internal code. Our QA engineers simulate real-world usage to validate features, workflows, and user interactions. This ensures the application meets business requirements and provides a seamless user experience across different environments.

Smoke testing services for early bug detection

Smoke testing is an essential preliminary phase in software quality assurance. It involves running a basic set of tests on a fresh build to verify that core functionalities work as expected. By catching critical issues early, smoke tests act as a gatekeeper—allowing only stable builds to move forward in the QA process. This minimizes rework, prevents complex defects later in development, and improves overall efficiency.

1

Verify & validate the veracity of essential features

2

Evaluate the new increments and change requests

3

Ensure continuity by testing the impact of increments on consolidated functionality

4

Test rational thinking & logic implementations of developers

Sanity testing in QA

Sanity testing quickly verifies that recent changes or bug fixes haven’t broken existing core features. Unlike full regression testing, it focuses on critical functionalities, helping developers catch glaring errors early and ensure system stability after updates. This fast check improves confidence in new builds, but should complement—not replace—comprehensive QA testing.

Efficiency and stability over time

Software is naturally prone to regressions and bugs, which can lead to premature obsolescence. By adopting agile practices, structured development processes, and automated testing, our QA teams ensure long-term stability and efficiency. This approach allows software to remain solid, scalable, and reliable over time.
